A new study by researchers from the University of New Mexico found that 34 percent of chronic pain patients enrolled in the study were able to cease using all prescription medications by the last six months of the 24-month observation period.

The study included 83 chronic pain patients enrolled in the state’s medical cannabis program, compared to 42 who were not. Another 36 percent of registered medical cannabis patients enrolled in the study were able to use fewer medications by the end of the study.
